Positional System with Options

igus has introduced new drylin products from the light pre-defined Positional System up to the preload prism slide. Expanding its range of linear guides for manual adjustments, the company offers further novelties such as the ball-pretensioned predefined positional system for stepped locking as well as the compact preload prism slide with pretensioned guide carriage. Depending on requirements, users can easily order their complete solutions for easy adjustments, rather than having to resort to own solutions or oversized linear guides. 'Manual adjustment' sounds like a very simple application, but it is often a major challenge. Especially when it comes to vertical adjustments such as kitchen equipment, headrests or fitness and rehabilitation equipment, in which the dead weight needs to bear light attachments. Here, recirculating ball guides are ruled out, because they are indeed very precise, but too expensive and cannot be held in place. They also require an external lubrication, which can lead to contamination of food or clothing. For such applications, igus has developed various linear guides, which can be adjusted according to user requirements via defined locking points or continuously by adjustable pretension. In the new drylin W stop motion pre-defined positional system, a plastic carriage moves on a profile and snaps into defined locking points. By means of a pretensioned ball between carriage and profile, which is held by a stainless steel spring, the carriage always stays in position and the dead weight also holds light attachments. The locking forces are dependent on the spring used as well as the bore, which like the rail length can be ordered for custom requirements. Due to the ball pretension in the plastic carriage, it sits on the lightweight aluminium profile virtually clearance free.
